Sorry but this is such bs. The claim that support stopped people from fragging has been denied by A LOT of pro players, and it's been used as an excuse whenever someone is having poor performances. Sure, there are reoles that won't get as many kills as some other ones, but, you can't use that excuse for not fragging at all.
In the end, CS is a game where you need to shoot headshots to win.
Edit: And I'm not a ''Taco hater'', I do think he's crucial for SK when he's performing.
